Answer:

Step-by-step explanation:

Because we are reflecting across the X-axis, the X coordinate does not change. On the other hand, the Y coordinate becomes its opposite. So we get:

(2, 4) -> (2, -4)

A geometric series like

$\displaystyle \sum_{n=1}^\infty \dfrac{1}{\alpha^n}$

Converges if and only if $|\alpha|>1$ . If this is the case, the sum equals

$\displaystyle \sum_{n=1}^\infty \dfrac{1}{\alpha^n} = \dfrac{1}{\alpha-1}$

So, in your case, you have convergence if and only if

$|2+a|>1 \iff 2+a>1 \lor 2+a-1 \lor a$

And if this is the case, the sum equals

$\displaystyle \sum_{n=1}^\infty \dfrac{1}{(2+a)^n} = \dfrac{1}{2+a-1} = \dfrac{1}{a+1}$
